Abstract

Abstract : The combination of π-conjugated fluorophores within a hybrid system gives rise to a triphenylamine-functionalized material [Zn(bpba)(NO3 )] (1 ) (Hbpba = 4-(bis(4-(pyridin-4-yl)phenyl)amino)benzoic acid). Abstract : The combination of π-conjugated fluorophores within a hybrid system gives rise to a triphenylamine-functionalized material [Zn(bpba)(NO3 )] (1 ) (Hbpba = 4-(bis(4-(pyridin-4-yl)phenyl)amino)benzoic acid). Compound1 features a 2D + 2D → 2D parallel polycatenation structure with 6 3 -hcb net. Photophysical studies revealed that the title phase showed superior sensitivity towards p -nitroaniline ( p -NA) with a low detection limit (down to ∼0.10 ppm). Specifically, following a new detection route, vapor-sensing experiments using a saturated ethanol solution of nitroaromatic isomers have been established for the first time. Highly sensitive and selective detection of p -NA by the proposed material with a rapid response time ( t = 30 s, QE > 90.0%) as compared to that via the control isomers ( t = 60s, QE < 6.0%) demonstrates an attractive feasible route and a promising luminescent sensor for nitroaromatic detection.
